Which of the following statements correctly describes the function of the right ventricle?

  1. It pumps blood to the body

  2. It pumps blood to the lungs for oxygenation

  3. It receives blood from the left atrium

  4. It controls blood flow from the aorta

The correct answer is: It pumps blood to the lungs for oxygenation

The right ventricle's primary role is to pump deoxygenated blood to the lungs for oxygenation. This process is crucial for gas exchange; in the lungs, carbon dioxide is released from the blood and oxygen is absorbed. The right ventricle receives the blood that has returned from the body via the right atrium and then contracts to push this blood through the pulmonary valve into the pulmonary artery, which leads to the lungs. This function is essential for maintaining the oxygen supply for the entire body, as oxygen-poor blood must be refreshed with oxygen before being circulated back out to the tissues and organs. Thus, the statement accurately emphasizes the specific and vital role of the right ventricle in the circulatory system.
